This pattern was inspired by similar patterns on the web as well as a life long love of math and science. I've always loved asking people to show me the right side and wrong side of a Moebius strip. ;)The first time I made this scarf, I kept shaking my head telling myself that I must be doing something wrong, there's no way this was going to work. But I was wrong!NOTE: To lessen confusion, even though it's a circular needle, the terms used to describe its two ends will be as if it was two separate needles.Approx. 150 to 200 g worsted yarn (5 1/2 to 7 1/2 oz), wool or wool blend preferred (like Fisherman's Wool or Wool-Ease)Circular needle of suitable size, 16 to 24 inchesGauge: approx. 5 stitches per inch with worsted, though it's not criticalCast On: Cast on 150 stitches, loosely. ................
